ARTIST Maturity Assessment Tool (MAT): Overview
Functional description
MAT’s objective is to assess the maturity of an application with respect to its migration to the
cloud performing the following activities:




Gather information about the current situation of the application willing to migrate
through a set of questionnaires (including questions at technical and business level).
Process the information (following a rule based approach).
Provide the set of results which comprises a) The positioning of the application including
initial and desired situation of the application, b) A set of High level recommendations on
how to perform the migration, c) A set of migration Goals
Compile the main relevant results of the ARTIST pre-migration phase [8] into an integrated
report.
Such an approach of assessing the maturity of an application regarding its maturity to be
migrated has not been supported or documented in literature.
The existing approaches [9], do not tackle the migration under different perspectives. They
face the problem addressing only specific perspectives of the migration (usually only technical
ones) and don’t provide tools to assess the impact of a potential migration. Existing solutions
adopt a big bang approach and starts directly with the migration process or they perform
specific personalize studies for a concrete migration project.
MAT provides a semi-automatic way of assessing an application (and a company) that is facing
a migration project even before the actual migration starts by delivering in advance key
information about how this migration will impact the company and the product both at
technical and business levels.
MAT has been implemented following an incremental approach adding features in the
different releases of the tool (M12, M18, M24, and M30).
This version of the prototype corresponds to the final official release. In this final version of the
prototype, several updates and improvements have been made (with respect to the D5.2.2
delivered in M24 [1]):






Improvements in the user interface providing new tabs and documentation describing the
lifecycle of the Maturity Assessment Tool.
Creation of the logic to implement linked question (some questions are only shown if
previous questions are answered in a specific way).
Generation of recommendations based on the answers and the corresponding
recommendation report.
Generation of a new report (iReport) where the most relevant results of the pre-migration
phase (Maturity Assessment Tool, Technical Feasibility Tool [10], Business Feasibility Tool
[11]) are compiled
Integration with the ARTIST repository [12]
Update of the MPT report with the incorporation of new questions and answer needed by
the MPT [13] to personalize the methodology.

Generate a set of recommendations based on the results of the maturity assessment.
Integrate all the pre-migration results in a single report.
Fitting into overall ARTIST solution
MAT is the first activity to be performed in the first phase of ARTIST. It is the tool that a user
who is adopting the ARTIST approach should use to start a migration project. This tool will
provide a first overview of the situation of the application and the company with respect to
the migration of that application to the cloud. This overview will help the user (and other tools
in ARTIST) to establish the basis and the starting point of the migration to apply the most
convenient improvement path.
In the ARTIST methodology, maturity assessment is the first activity to be performed. This
assessment, including technical and business evaluation can be done using the MAT in the premigration phase proposed by the methodology (see figure 1):

The MAT is part of the Modernization Assessment components package, indeed is one of the
components inside this package (see figure 2).
MAT interacts with the two components of modernization assessment (BFT and TFT) as well as
with other tools in the ARTIST tool chain (see figure 3):

Target Specification Tool (Modernization Methodology): MAT provides the set of
Migration Goals related to the target platform selection.
Non-functional Requirements Assessment Tool: MAT will provide the part of the
migration goals referred to the non-functional requirements.
Business Feasibility Tool: MAT will provide the set of Migration Goals and relevant
information form the user.
Technical Feasibility Tool: MAT will provide the set of Migration Goals and relevant

Components description
MAT is composed of the following components:




Services: This is the main communication component of the Maturity Assessment tool. It
provides the interface between the Server and the HTML5 client.
Structures: This component contains the structures of the inputs and outputs models that
the MAT uses. It also has the functionality for generating the output structured formats
(XML, JSON).
Tools DB: In this component is where the logic of the Maturity Assessment tool is
implemented. This component calculates the scores and the levels of each questionnaire
based on the best practices stated by the different standards. It also provides the
questions ordered by category and types.
Database: This is the data access component of the Maturity Assessment tool. It provides
an interface for accessing the MySQL Data Base.
Data base model
The following picture represents the data base model of the Maturity Assessment tool:

The matReport component has been implemented over the BIRT technology [14]. BIRT is an
open source component under the EPL licence. This allows its commercial usage. We have
